Those groups were Turkic, not Turks. We are Indo-Europeans. Back in the days the demographics were not the same as now. It's so dumb, like the Indians who claim they are Aryians ,when in fact all of those so-called Ariyans moved to Europe. You can't spell Hungarian and Bulgarian without Arian :D anyways. Jokes aside, if you check maps from back in the days when the Ottomans were a little state bellow Turkey,they started occupying and getting manpower from the other tribes around them and decided to attack the Eastern Roman Empire in their biggest crisis.
Also daily reminder the founder of Turkey is a Greek with Bulgarian roots from his grandfather side kekw.
